Product Description

C18-Low PH is designed for use at low pH condition, which consists of two very bulky hydrophobic protective groups to prevent siloxane bond from hydrolysis at low pH condition. So this column is extremely stable in very low pH mobile phase and at high temperature, even at the lowest pH 0.5, making it the most stable C18 for low pH application in the market. Because it is not end-capped and has more surface silanols, ithas more retention for some early eluted polar compounds, and provides some different selectivity than traditional C18. C18-Low PH is the most polar C18 among all the C18 products.

Features

1. Not end-capped, prevent siloxane bond from hydrolysis at low pH condition.

2. Endure 100% water as the mobile phase, similar to “C18-Aqueous”.

3. Best peak shape for polar compounds analysis.

4. Exceptional lifetime at low pH (0.5-8.0) and high temperature.

5. 300Å C18-Low PH is exclusively used for separation of polypeptide and protein.
